Can you help us solve this math problem? We can't agree:

If Tom and Bess are brother and sister, and Tom says he has as many sisters as brothers and Bess says she has twice as many brothers as sisters, how many girls are there in the family?

Hint: for any and all word problem

Name stuff (copyright tkhunny)

Assume that:

B = # boys in the family

G = # girls in the family

Tom says he has as many sisters as brothers

so

B-1 = G......................................(1)

formulate the other equation from the other condition and solve for 'B' and 'G'.
